[Mental health activities following the Great East Japan Earthquake in the stricken coastal area of Iwate Prefecture].
Since the Great East Japan Earthquake, many survivors have experienced psychological crises because of the immense damage in the coastal area of Iwate Prefecture. Mental care teams started activities in March 2011 along the coast of Iwate. We employed a mid- to long-term care model. In February 2012, we set up the Iwate Mental Care Center and built a long-term support system in Iwate Prefecture.
متن کاملControls on alluvial fan long - profi les
Water and debris fl ows exiting confi ned valleys have a tendency to deposit sediment on steep fans. On alluvial fans where water transport of gravel predominates, channel slopes tend to decrease downfan from ~0.10–0.04 to ~0.01 across wide ranges of climate and tectonism. Some have argued that this pattern refl ects grain-size fi ning downfan such that higher threshold slopes are required just...
متن کاملThe Role of Climatic Change in Alluvial Fan Development
Alluvial fans develop at the base of drainages where feeder channels release their solid load (Blair and McPherson, 2009; Leeder et al., 1998; Harvey et al., 2005). A classic fan-shape forms where there is a well-defined topographic apex. Multiple feeder channels, however, often blur the fan-shape resulting in a merged bajada. Alluvial fans can be found in almost all terrestrial settings. These...
متن کاملRegional Difference on Road Recovery in Iwate Prefecture Following the 2011 Tohoku Earthquake
In a previous study, we have calculated the usable road distance in the southern coastal area of Iwate Prefecture following the 2011 Tohoku Earthquake. In this context, a usable road is one on which at least one vehicle has been probed during the observation period. If the accumulative usable distance up to September 30, 2011 is considered as 100%, then the percentage of the usable road distanc...
متن کاملAnalysis of Vehicle Tracking Maps in Iwate Prefecture Following the 2011 Tohoku Earthquake
We calculated the usable distance of the main roads in the coastal area of Iwate prefecture following the 2011 Tohoku Earthquake. Calculations were based on a vehicle tracking map built from G-BOOK telematics data using QGIS, an open source geographic information system. The main findings are as follows. (1) The change in the accumulative usable road distance ratio during the research period di...
